Looks like you'd be better off making an Accumulator that knows what
to do.
>>> class Accumulator(list):
... def flush(self):
... if len(self):
... print "Flushing items: %s" % self
... del self[:]
...
>>> lines = [
... "spam", "eggs", "FLUSH",
... "beans", "rat", "FLUSH",
... "strawberry",
... ]
>>>
>>> acc = Accumulator()
>>> for line in lines:
... if line == 'FLUSH':
... acc.flush()
... else:
... acc.append(line)
...
Flushing items: ['spam', 'eggs']
Flushing items: ['beans', 'rat']
>>> acc.flush()
Flushing items: ['strawberry']
>>>
